I have a combobox component that can draw on available properties such as "Class" and "MaxHeight." However, when I try to implement comboboxes, I see no way to disable them. Below is a portion of the RenderComboBox method. I can only avoid the error by commenting out "d.AddAttribute(302, "Enabled", "false");"

                RenderFragment item = d =>
                    if (RowCount == 0) { RowCount= 20; }
                        d.AddAttribute(300, "MaxHeight", $"{(RowCount * 22).ToString()}px");
                        d.AddAttribute(301, "Class", "telCombo");
                        d.AddAttribute(302, "Enabled", "false");

The above code earns me the message

"Object of type 'Telerik.Blazor.Components.ComboBoxPopupSettings' does not have a property matching the name 'Enabled'."

Indeed, when I look it up, the list of inherited members has nothing for enabling/ disabling the feature. How can i disable it?

Hello Doug,

You can disable the combobox input itself, rather than the popup. To do this, you need to set the Enabled parameter to false. Here is a REPL example, where you can see the difference between an enabled and a disabled ComboBox:

Since your attempt to set the Enabled parameter to the ComboBoxPopupSettings tag rather than the TelerikComboBox, you receive an exception, as the popup does not indeed have such a parameter. To resolve this, simply move the Enabled declaration to its parent.
